Answer 1

I assume that you want to both access the Internet with one AirPort Express Base Station (AX) and stream iTunes to the other AX at the same time. To do so, you just need to reconfigure the second AX as a wireless client.
To do so ...
Either connect to the AX's wireless network or connect directly, using an Ethernet cable, to the Ethernet port of the AX, and then using the AirPort Utility in "Manual Setup" mode, make the following changes:
AirPort > Wireless
o Wireless Mode: Join a wireless network
o Network Name: <existing AX's wireless network>
o Wireless Security: <select the encryption type of the existing wireless network>
o Wireless Password: <enter the existing wireless network password>
o Verify Password: <re-enter the existing wireless network password>
Music
o Enable AirTunes (checked)
o iTunes Speaker Name: <enter desired speaker name>
o iTunes Speaker Password: (optional)
o Verify Password: (optional)
o Click Update to write the new settings to the AX
In iTunes:
iTunes > Preferences... > Advanced > General
o Look for remote speakers connected with AirTunes (checked)
